[0079] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0080] In related technologies, cup lids often use press-type, rotation-type, or push-pull-type mechanisms to control the opening and closing of the drinking spout 11. These traditional cup lids have problems with insufficient sealing performance and inconvenient operation in actual use.

[0081] Therefore, embodiments of this application provide a toggle-type direct drinking cup lid and a direct drinking cup, aiming to provide a toggle-type direct drinking cup lid with simple structure, excellent sealing performance and convenient operation.

[0082] like Figures 1 to 8 As shown, this embodiment of the invention provides a toggle-type direct drinking cup lid, including a lid body 1 and a switch knob 2. The lid body 1 is provided with a drinking spout 11 and a guide protrusion 12. The switch knob 2 consists of an upper toggle member 21 and a lower toggle member 22. The upper toggle member 21 is located at the top of the lid body 1, and the lower toggle member 22 is located at the bottom of the lid body 1 and is synchronously connected to the upper toggle member 21.

[0083] The lower pusher 22 is provided with a pre-tightening protrusion 221, which has an arc surface that abuts against the guide slope 121a. The bottom of the cup lid body 1 is provided with a guide latch protrusion 12, which includes a guide block 121. The guide blocks 121 are spaced apart, and the gaps form a latching opening 121b into which the pre-tightening protrusion 221 engages. The guide block 121 is provided with a guide slope 121a.

[0084] The first sealing element 23 is located on the side of the lower pusher 22 near the cup lid body 1 and is matched with the drinking spout 11 to achieve a seal on the drinking spout 11.

[0085] Working principle:

[0086] Sealing the drinking spout 11: When the upper pusher 21 is pushed in the positive direction, the lower pusher 22 rotates synchronously. When the arc surface of the pre-tightening protrusion 221 contacts the guide slope 121a of the guide locking protrusion 12, continue pushing. The upper pusher 21 drives the lower pusher 22, so that the pre-tightening protrusion 221 is locked into the holding port 121b of the guide locking protrusion 12 under the guidance of the guide slope 121a. The pre-tightening protrusion 221 is locked in the guide locking protrusion 12. At this time, the distance between the upper pusher 21 and the lower pusher 22 decreases, and the first sealing member 23 seals the drinking spout 11. The upper pusher 21 and / or the lower pusher 22 cover the drinking spout 11 to achieve a seal.

[0087] To open the drinking spout 11: Move the upper lever 21 in the forward or reverse direction, and the lower lever 22 will rotate synchronously. The pre-tightening protrusion 221 will disengage from the retaining port 121b of the guide protrusion 12. You can feel the pre-tightening protrusion 221 disengaging from the retaining port 121b or feel a distinct tactile feedback. Continue to move the upper lever 21, and the distance between the upper lever 21 and the lower lever 22 will increase. The first seal 23 will leave the drinking spout 11, and the opening will be completed.

[0088] In one embodiment, one end of the upper lever 21 is provided with a post 211, which has a threaded hole 242 and a limiting rib 211b on its outer wall. One end of the lower lever 22 is provided with a socket 222, the inner wall of which has a limiting insertion joint 222a corresponding to the limiting rib 211b, and a screw 223 matching the threaded hole 242 is inserted into the socket 222. During installation, the post 211 is inserted into or tightly fitted into the socket 222 of the lower lever 22 through the lever connection port 13 on the cup lid body 1. The limiting rib 211b on the post 211 is embedded in the limiting insertion joint 222a, and the screw 223 is connected to the threaded hole 242 on the post 211 to ensure synchronous connection of the upper lever 21 and the lower lever 22. A second sealing element 131 is arranged at the lever connection port 13 to prevent liquid leakage from the lever connection port 13. When the pre-tightening protrusion 221 is held by the guide protrusion 12, the upper pusher 21 and / or the lower pusher 22 cover the drinking mouth 11, and the first sealing member 23 seals the drinking mouth 11.

[0089] In another embodiment, the insert 211 has a connecting hole 211a inside, and a tightening reinforcement 24 is provided inside the connecting hole 211a. A threaded hole 242 is provided on the tightening reinforcement 24, and the outer wall of the tightening reinforcement 24 is provided with an anti-tensile anti-slip gear 241, which is provided with several anti-tensile anti-slip racks. The threaded hole 242 is provided inside the tightening reinforcement 24. The main purpose of designing the tightening reinforcement 24 is to achieve precise synchronization and precise stopping of the upper lever 21 and the lower lever 22 during rotation, and to enhance the connection stability between the two, effectively preventing slippage; increasing the connection strength, it enables the switch knob 2 to withstand greater torque or torque, preventing loosening due to wear during long-term use. The tightening reinforcement 24 is provided with an anti-tensile anti-slip gear 241 to further increase torque. In detail, the tightening reinforcement 24 is a copper nut structure, and the anti-tension anti-slip gear 241 and the anti-tension anti-slip rack are both part of the copper nut. The insert 211 and the socket 222 are both plastic parts or plastic materials. The design of the copper nut can increase the friction between it and the plastic, making it less likely to loosen, strip, or even detach due to excessive torque between the screw and the insert 211. Furthermore, the design of the anti-tension anti-slip gear 241 and the anti-tension anti-slip rack can increase the tensile strength between the copper nut and the insert 211 (plastic part), further preventing the copper nut from loosening due to excessive tension from the screw and the insert 211 during use. During installation, the tightening reinforcement 24 is placed in the connecting hole 211a of the insert 211. Specifically, the tightening reinforcement 24 is fixed in the connecting hole 211a by in-mold injection molding. The insert 211 is inserted into or tightly fitted into the insertion port 222 of the lower pusher 22 through the pusher connection port 13 on the cup lid body 1. The limiting rib 211b on the insert 211 is embedded in the limiting insertion joint 222a to ensure the synchronous connection of the upper pusher 21 and the lower pusher 22. The screw 223 is inserted from the bottom of the lower pusher 22 into the insertion port 222 on the lower pusher 22 and connected to the threaded hole 242 on the tightening reinforcement 24. A second sealing element 131 is arranged at the pusher connection port 13 to prevent liquid leakage from the pusher connection port 13. When the pre-tightening protrusion 221 is held by the guide protrusion 12, the upper pusher 21 and / or the lower pusher 22 cover the drinking mouth 11, and the first sealing member 23 seals the drinking mouth 11.

[0090] The beneficial effects of this sliding direct-drinking cup lid design:

[0091] Improved sealing performance. Specifically: The cup lid body 1 is provided with a drinking spout 11 and a guide latch 12; the switch knob 2 includes an upper lever 21 and a lower lever 22, which, through the cooperation of a pre-tightening protrusion 221 and the guide latch 12, reduce the distance between the upper lever 21 and the lower lever 22. When the pre-tightening protrusion 221 is engaged with the guide latch 12, the upper lever 21 and / or the lower lever 22 seal the drinking spout 11, and the first sealing element 23 seals the drinking spout 11. This design ensures that the drinking spout 11 is reliably sealed in the closed state, preventing liquid leakage and improving sealing performance.

[0092] Easy to operate. Specifically: the upper lever 21 is located at the top of the cup lid body 1, and the lower lever 22 is located at the bottom of the cup lid body 1, with the two connected synchronously. The user only needs to move the upper lever 21 to control the opening and closing of the drinking spout 11. The cooperation between the pre-tightening protrusion 221 and the guide protrusion 12 provides clear tactile feedback. Users can quickly complete the operation with one hand, making it suitable for various scenarios such as walking and driving, thus improving ease of use.

[0093] The structure is simple and easy to clean. Specifically, the cup lid consists of a few parts, including the lid body 1, upper lever 21, lower lever 22, pre-tightening protrusion 221, guide latch protrusion 12, and a sealing element. The structural design is simple. The synchronous connection of the upper and lower levers 22 facilitates disassembly and assembly. This reduces production costs, allows users to easily disassemble and clean the cup lid, maintains hygiene, and improves the user experience.

[0094] Improved durability. Specifically: the design of the pre-tightening protrusion 221 and the guide protrusion 12 ensures the stability of the upper and lower levers 21 during operation, reducing wear between components. The synchronous connection structure improves the overall strength of the assembly. This enhances the durability of the cup lid, extends the product's lifespan, and reduces maintenance and replacement costs.

[0095] To prevent accidental operation, the locking design of the pre-tightening protrusion 221 and the guide protrusion 12 provides clear positioning and stopping functions during opening and closing, allowing users to judge the operating status by feel. This reduces the possibility of accidental operation and improves safety.

[0096] Through the above-mentioned technical means, the present invention effectively solves the problems of poor sealing performance, inconvenient operation, and complex structure in the prior art, and achieves the technical effects of simple structure, reliable sealing, convenient operation, easy cleaning and high durability, thus meeting users' needs for high-quality direct drinking cup lids.

This not only ensures sealing performance but also improves the stability of the assembly process and facilitates a smooth transition between the outer wall of the decorative connector 33 and the outer wall of the cup body (outer layer wall 302).

[0123] A viewing cup includes a cup body and a lid. The cup body is the viewing cup body described in the aforementioned embodiments, and the lid is the toggle-type direct-drinking cup lid described in the aforementioned embodiments. Wherein:

[0124] The cup lid body 1 has a drinking spout 11 and a guide bracket 12 for user convenience.

[0125] The switch knob 2 consists of an upper switch 21 and a lower switch 22. It is guided and held by the guide protrusion 12, which can effectively control the opening and closing of the drinking port 11, and ensure the sealing of the drinking port 11 through the sealing component.

[0126] A method for producing a viewing cup, comprising the following steps:

[0127] Preparatory steps: First, prefabricate the window 304 on the double-layered cup body 3 so that the window 31 component can be installed later.

[0128] First assembly step: Wrap the edge sealing ring 32 around the window body portion 311 of the viewing window 31 and abut it against the first abutment portion 312. Specifically, embed the edge sealing ring 32 into the sealing seam 312b of the first abutment portion 312. Insert the window body portion 311 of the viewing window 31 into the mounting window 304 from the cup cavity 303 until a gap 313 is formed between the window body portion 311 and the mounting window 304, and make the first abutment portion 312 and the edge sealing ring 32 abut against the inner wall 301 of the cup body to ensure sealing.

[0129] The second assembly step is to insert the insert edge 331 of the decorative connector 33 into the slot 313 formed between the window body 311 and the mounting window 304. Specifically, the insert edge 331 is embedded into the insert edge slot 312a of the first abutment part 312 until the second abutment part 332 of the decorative connector 33 abuts against the outer wall 302 of the cup body. Specifically, the second pre-tightening slope 333 of the second abutment part 332 abuts against the first pre-tightening slope 304a of the mounting window 304 until the outer wall of the decorative connector 33 is flush with the outer wall of the cup body 3, forming a stable connection structure.

[0130] Fixing steps: The decorative connector 33 is firmly connected to the window 31 assembly using ultrasonic welding technology to ensure that the window 31 does not loosen and maintains a good seal between it and the cup body.

[0131] The window cup body and window cup described in this solution solve the technical problems in the prior art in the following ways:

[0132] Improved sealing: By setting an edge sealing ring 32 on the first abutment portion 312 of the viewing window 31, the sealing between the viewing window 31 and the cup body is ensured, avoiding liquid leakage problems.

[0133] Enhanced stability: The inner and outer clamping structure formed between the window 31 and the decorative connector 33 ensures that the window 31 is firmly installed after being fixed to the decorative connector 33 by ultrasonic welding, making it less likely to fall off and improving the durability of the product.

[0134] Enhanced aesthetics: The decorative connector 33 is flush with the outer wall of the cup, ensuring a smooth and beautiful appearance and providing a better user experience.

[0135] Simplified production process: The use of ultrasonic welding technology simplifies the production process, ensures a stable connection between the viewing window 31 and the cup body, and reduces production costs.

[0136] User needs are met: The window cup design not only has a heat preservation effect, but also allows users to clearly observe the state or volume of the liquid inside the cup, increasing the functionality of the product.

[0137] like Figures 18-21 As shown, this embodiment of the invention provides a detachable two-color drinking cup, mainly comprising a lower cup body and an upper cup body 4. The lower cup body and the upper cup body 4 are detachable via a threaded connection. Specifically, the upper cup body 4 includes a lower non-transparent portion 41 and an upper transparent portion 42. The non-transparent portion 41 and the transparent portion 42 are integrally molded using a two-color injection molding process to form a cup body with a two-color structure having the non-transparent portion 41 and the transparent portion 42. The transparent portion 42 is located in the upper half of the upper cup body 4, and the non-transparent portion 41 is located in the lower half. A drinking spout 421 is provided at the top of the transparent portion 42, and a cap 43 is fitted onto the drinking spout 421. The cap 43 consists of a hard inner cap 431 and a soft outer cap 432, wherein the soft outer cap 432 has an anti-slip function.

[0138] The lower cup body and the upper cup body 4 are connected by threads. The drinking spout 421 of the upper cup body 4 is equipped with a hard rubber inner cap 431. The inner surface of the hard rubber inner cap 431 has internal threads that can match the external threads on the lower cup body. The outer surface of the hard rubber inner cap 431 is covered with a soft rubber outer cap 432, which has a certain anti-slip effect, making it convenient for users to hold the cap 43 and rotate it. During use, users can loosen or tighten the cap 43 by rotating it to achieve the purpose of sealing or opening.

[0139] To ensure the water cup's sealing performance during use, a sealing position is provided at the end of the non-transparent part 41 near the transparent part 42, and a sealing clamp 412 is provided on the sealing position. This sealing clamp 412 is used to cooperate with the sealing structure of the transparent part 42 of the upper cup body 4 to form an effective seal and prevent liquid leakage. The sealing clamp 412 is integrally injection molded with the transparent part 42 and the non-transparent part 41, ensuring the stability and reliability of the sealing performance.

[0140] To ensure the stability of the connection between the upper cup body 4 and the lower cup body and to facilitate demolding during production, the non-transparent part 41 has a first abutting surface 413 and a first limiting draft surface 414 at an angle to each other at one end near the transparent part 42. The transparent part 42 has a second abutting surface 422 abutting against the first abutting surface 413 and a second limiting draft surface 423 abutting against the first limiting draft surface 414 at one end near the non-transparent part 41. This limiting design not only provides accurate positioning during assembly but also ensures smooth demolding during production, avoiding mold jamming problems.

[0141] The non-transparent portion 41 and the transparent portion 42 of the upper cup body 4 are produced using a two-color injection molding process. This process allows the non-transparent portion 41 and the transparent portion 42 to be molded in a single injection, ensuring a seamless and strong connection between the two parts. This process guarantees structural stability while achieving an aesthetically pleasing appearance. The transparent portion 42 allows for easy observation of the liquid level inside the cup, while the non-transparent portion 41 provides good strength and pressure resistance.

[0142] How to use:

[0143] Filling with water: Users can separate the upper cup body 4 from the lower cup body and fill the cup directly from the tap through the large opening of the lower cup body. The larger opening of the lower cup body allows for quick filling, reducing the inconvenience caused by the small opening of traditional cups.

[0144] Drinking water: After filling with water, screw the upper cup body 4 and the lower cup body together. With the non-slip design of the soft rubber outer cap 432, the user can easily unscrew the cap 43 and drink water through the drinking spout 421.

[0145] Cleaning: Thanks to the split design, users can separate the lower cup body from the upper cup body 4 for easy and thorough cleaning, avoiding the inconvenience of cleaning in one-piece cup designs.

[0146] The transparent part 42 can be made of a food-contact plastic material, such as a copolyester material called Teflon. Tritan (or other transparent plastics) to ensure safe use. The soft rubber outer cover 432 can be made of soft rubber materials of different hardness as needed to further improve grip comfort and anti-slip performance.

[0147] In another embodiment, the lower body of a split-type two-color drinking cup is the viewing cup body described in this solution. Specifically, the viewing cup body includes:

[0148] The cup body 3 has a side window 304 and a cup cavity 303 that communicates with the side window 304. One end of the cup cavity 303 is open.

[0149] The window 31 includes a window body portion 311 and a first abutment portion 312 formed on the edge of the window body portion 311;

[0150] The edge sealing ring 32 is disposed on the first abutment portion 312; and

[0151] The decorative connector 33 includes an insert portion 331 and abutment portion 332;

[0152] The cup body 3 is detachably connected to the open end near the cup cavity 303 and the end near the non-transparent part 41 of the upper cup body 4. The window part 311 is inserted into the window 304 and a slot 313 is formed between it and the window 304. The first abutting part 312 abuts against the inner wall of the cup body 3 through the sealing ring 32. The inserting part 331 is inserted into the slot 313. The second abutting part 332 abuts against the outer wall of the cup body 3.

[0153] This invention presents a detachable, two-color drinking cup. Through a rational structural design, sealing design, threaded connection, and two-color injection molding process, it solves the problems of inconvenient liquid level observation, difficulty in filling with water, and cap slippage in existing technologies. Its easy disassembly method makes cleaning more convenient, while also improving the comfort and stability of the drinking process. This invention has broad application prospects and is suitable for various drinking needs in daily life.
